Shell-code is a piece of object codes that can be injected into the executable stack to get the execution access...Shell-code is so called because it is basically used to get a shell (/bin/bash).. We'll see how make a simple exit shell-code..

This article assumes basic knowledge of Assembly x86 as prerequisites for this article

Just run that command for now.. I'll write a tutorial on objdump soon!!...

Now as we see there are lots and lots of nuls out there in the opcodes..

So we need to remove that because as we will be using this shellcode to run it in a executable stack so..The program will be reading the opcodes only till it finds a null (assume the functionallity like that of strcpy()).. As it finds a null it will return to the main program..
